Google Earth is a virtual globe program that was originally called Earth Viewer and was created by Keyhole, Inc. It maps the earth by the superimposition of images obtained from satellite imagery, aerial photography and GIS 3D globe. It is available under three different licenses: Google Earth, a free version with limited functionality; Google Earth Plus ($20 per year), which includes additional features; and Google Earth Pro ($400 per year), which is intended for commercial use.
There are many good things in this regard e.g. it'll be useful for each person who wanna know more about geographic points of each place in all over the world and very useful to know more about your living place.But in the new version of this abality, you can zoom and see persons with their motion.
